Element Path: <cwt><CORE><ambientLightSensor>
The Ambient Light function, which is common for the STN backlight and the external light, measures the ambient light with a given sampling periodicity and calculates a brightness value.
Attributes
hysteresis
Description: | The ambient light change, in percentage above or below the threshold, needed to change the backlight brightness. This is a filter function to prevent state change every time the ambient light is measured while its brightness is close to the threshold. |
samplingPeriod
Range: | 1 – 65535 (minutes) |
Description: | Measuring period. |
threshold
Description: | The threshold that determines if it is dark or not. If the threshold = 500 ambient light below 500 is considered dark. |
type |  |
Description: | Type of ambient light sensor used.
AVR is used for CWT doors
VEML7700 is used for Strada doors |
